EXPEDITION TO SOKOTRA : NEW SPECIES. a 
termen, where they are somewhat densely crowded ; another narrow line 
follows the upper edge of the fold and the dorsal space below the fold is 
almost entirely suffused with pale greyish brown ; cilia greyish brown, with 
a slight ochreous tinge, giving them a brighter appearance than the wing- 
markings. Exp. al. 12 mm. Hind-wings brownish grey, the cilia as in the 
fore-wings. Abdomen greyish, anal tuft whitish cinereous. Legs dirty 
whitish. 
Type 4 (13379) Mus. Wlsm. 
Habitat. Sokotra ; Hadibu Plain (11. XII. 98) ; Adho Dimellus (3,500 ft., 
12. IT. 99). 
(9) Scythris, sp. 
Habitat. Sokotra: Hadibu Plain (15. XII. 98)—Mus. Wlsm., 13375. 
A single specimen in poor condition, but distinct from those now 
described. 
(10) Scythris (!) pectinicornis. 
Antenne with a strong closely packed pecten on the basal joint ; biciliate 
in both sexes (¢ 1-14, @ rather less); pale cinereous. Palpi, ¢ recurved to 
the level of the vertex, the terminal joint shorter than the median; 2? more 
slender and less recurved; whitish cinereous. Head and Tf. horax whitish 
cinereous. Fore-wings whitish cinereous, profusely dusted with brownish grey 
scaling, evenly distributed throughout, except a little beyond the middle of 
the fold where it appears somewhat concentrated ; cilia whitish cinereous, 
becoming brownish ochreous about the tornus. Exp. al. 6 12, 9 11 mm. 
Hind-wings vosy grey; cilia pale brownish ochreous. 4bdomen whitish 
cinereous. Legs, hind tibie pale brownish ochreous, hind tarsi whitish 
cinereous. 
Type & (13383); 2 (13382) Mus. Wism. 
Habitat. Sokotra; Hadibu Plain (15. XII. 98). 
Genostele, gen. nov. 
Type. Genostele reniger, ///Ism. 
Antenne (Q) 2, simple, tending to slight serrations before the apex. 
Ocelli absent. Maxillary Palpi well-developed, porrect, inflected. Lalial 
Palpi long, recurved, the median joint slightly roughened towards the apex ; 
terminal joint scarcely shorter than the median, slender acute. Head and 
face clothed with loose scales. Thorax smooth. Fore wings four times as long 
as broad, elongate, costa slightly arched, the apex depressed, rounded, termen 
oblique. Newration, 11 veins, (7 and 8 coincident) to costa ; the other veins 
separate. Hind-wings not broader than the fore-wings, somewhat rounded at 
the apex, not emarginate. Newration, 8 veins ; 3 and 4 almost connate, 6 and 
7 separate and almost parallel, 6 about equidistant from 5 and 7. Abdomen 
normal. Legs, hind tibize somewhat hairy above. 
This genus differs from Cerostoma, Ltr., in the separation of veins 6 and 7 
of the hind-wings and from Plutella, Schrk., in the remoteness of vein 6 from 5 
as also in the coincidence of veins 7 and 8 of the fore-wings, but in general 
appearance and structure its affinity would be to these genera. The genus 
Ancylometis, Meyr., from Mauritius appears to approach Genostele in some 
respects, particularly in the coincidence of veins 7 and 8 of the fore-wings, 
but if Meyrick is correct in describing it as having vein 5 of the hind-wings 
= mre to, or coincident with 4, it must be regarded as sufficiently 
istinct.
